Goto a new relative route.

This specifies a path relative to the node outlet: the Navigator or PageControl at, or up from, node. The path fragment starting at that outlet will be replaced with the new path. A goto is done on this resulting path.

<Router ux:Name="router"/>
<Navigator>
    <Navigator ux:Template="one" ux:Name="inner">
        <Panel ux:Template="a"/>
        <Panel ux:Template="b"/>

If the current route is one/a a call to gotoRelative( inner, "b" ) will go to the route one/b. The relative path replaces the path starting at inner.
